+MediaTek pericfg Controller
+
+The pericfg controller contains miscellaneous registers for controlling
+clocks, resets and bus settings.
+
+Required properties:
+- compatible: must be one of:
+ mediatek,mt8135-pericfg
+ mediatek,mt8173-pericfg
+- reg: Address range for the pericfg controller
+
+Example:
+
+ pericfg: pericfg@...03000 {
+ #reset-cells = <1>;
+ #clock-cells = <1>;
+ compatible = "mediatek,mt8135-pericfg";
+ reg = <0 0x10003000 0 0x1000>;
